Lookup label: IDEAL-D
Drawing use: Schematic
Reference families: Manufacturer

Controls an external transistor to obtain the documented low-loss directional or reverse-blocking power path.

## What it represents

Controls an external transistor to obtain the documented low-loss directional or reverse-blocking power path.
On a schematic, identify the input/output sensing nodes and external MOSFET gate/source connections and trace the protected supply path and reverse-current control. Keep the component tag and signal/reference names consistent across the control drawing, terminal schedule and device documentation.
An ideal-diode controller is an active circuit with operating limits; the term does not mean a lossless physical diode.
The preview is an independently drawn educational functional reference. Add the selected component’s actual power pins, terminal numbers, timing or analogue reference details when producing a construction drawing.

## How to read it

- Identify the input/output sensing nodes and external MOSFET gate/source connections.
- Trace the protected supply path and reverse-current control.

## Information to show or reference

- Label the input/output sensing nodes and external MOSFET gate/source connections.
- Cross-reference the protected supply path and reverse-current control.
- Add the selected device or circuit documentation revision, power/reference connections and project signal convention.

## Important distinction

An ideal-diode controller is an active circuit with operating limits; the term does not mean a lossless physical diode.

## Facts

- Common schematic mnemonic: IDEAL-D — descriptive only; project/device documentation defines reference designations.
- Terminal / interface focus: The input/output sensing nodes and external MOSFET gate/source connections
- Artwork scope: Original educational functional/circuit reference; not a selected product pinout.
